Den foreliggende opfindelse vedrører en forbindelsesdel til trækonstruktionsarbejde og en fremgangsmåde til montering af en sådan forbindelsesdel i en bygningskomponent af træ.The present invention relates to a connecting part for wood construction work and to a method for mounting such a connecting part in a wooden building component.
Trækonstruktioner kræver kraftoverførende forbindelser, som 5 kan modstå store trækbelastninger i længderetningen for tilgrænsende træbjælker. Der er allerede blevet gjort betydelige anstrengelser for at udvikle forbindelseselementer, som er meget stabile under belastning, lette og billige at fremstille og endvidere tillader hurtig samling. Således 10 kendes der en kraftoverførende træforbindelse (tysk offentliggørelsesskrift nr. 33 18 751), som i alt væsentligt har et rørformet legeme, der kan indskubbes i en blindboring i en træbjælke og holdes i denne blindboring ved hjælp af ståltappe, som drives radialt udefter og ind i træet. Det 15 har vist sig, at denne træforbindelse i vid udstrækning imødekommer de ovenfor nævnte krav, men at denne kendte konstruktion stadig har behov for forbedring, idet det rørformede legeme og ståltappene, som kræves til fastgørelse af det rørformede legeme, er forholdsvis komplicerede og 20 tidskrævende at fremstille, og idet der yderligere kræves et kompliceret drivværktøj til fastgørelse af ståltappene.Timber structures require force-transmitting connections that can withstand large longitudinal tensile loads for adjacent timber beams. Substantial efforts have already been made to develop connecting elements which are very stable under load, lightweight and inexpensive to manufacture and furthermore allow for fast assembly. Thus, a power transmitting wood connection (German Publication No. 33 18 751) is known, which has essentially a tubular body which can be pushed into a blind bore in a wooden beam and held in this blind bore by means of steel pins driven radially outwards and into the tree. It has been found that this wood joint extends largely to the above mentioned requirements, but that this known construction still needs improvement as the tubular body and steel pins required to attach the tubular body are relatively complicated and time-consuming to produce, and further requiring a complicated drive tool for securing the steel pins.
Den kendte forbindelsesdel fastgøres på forholdsvis kort tid, men denne proces involverer så betydelige anstrengelser, at der til etablering af et stort antal forbindelser 25 kræves en betydelig samlet tid.The known connection part is fixed in a relatively short time, but this process involves such considerable effort that a considerable number of time is required to establish a large number of connections.
Til grund for opfindelsen ligger det problem at tilvejebringe en forbindelsesdel til trækonstruktionsarbejde, hvilken del er billig at fremstille, kan fastgøres til en aktuel bygningskomponent af træ i løbet af kort tid og kan 30 modstå overordentlig store trækbelastninger.In accordance with the invention, there is a problem in providing a connection part for wood construction work which is inexpensive to manufacture, can be fixed to a current building component of wood in a short time and can withstand extremely large tensile loads.
Løsningen på dette problem er angivet i krav 1. I sin mest simple udførelsesform har forbindelsesdelen ifølge opfindelsen en indsatsdel eller et indsatslegeme med en indre endeplade, som senere fastgøres i nærheden af bunden af 35 blindboringen, samt en kraftoverførende stang, som er fast- 2The solution to this problem is set forth in claim 1. In its simplest embodiment, the connector according to the invention has an insert member or insert body with an inner end plate which is subsequently secured in the vicinity of the bottom of the blind bore, and a power transmitting rod which is secured.

gjort til pladen fx ved svejsning og i det mindste én stangformet dyvel, som trænger ind i blindboringen, samt en støbemassedel. Disse dele udgør en sammensat blok, der som forbindelsesdel er i stand til at kunne modstå ekstreme 5 trækbelastninger.made to the plate for example by welding and at least one rod-shaped dowel which penetrates the blind bore, as well as a casting member. These parts form a composite block which, as a connecting part, is capable of withstanding extreme tensile loads.
Hvis der kun tilvejebringes én kraftoverførende stang, som derefter hensigtsmæssigt svejses til centrum af den indre endeplade, kan denne stangs anden ende rage ud af blindboringen for at tillade fastgøring til andre forbindelses-10 dele..Når denne forbindelsesdel udsættes for;træk, overføres kraften via den kraftoverførende stang til den indre en^deplade, fra denne til støbemasselegemet og videre fra dette delvis direkte til blindboringens væg og i øvrigt også for størstedelens vedkommende via ståldyvelerne til 15 træet.If only one power transmitting rod is provided, which is then conveniently welded to the center of the inner end plate, the other end of this rod may protrude from the blind bore to allow attachment to other connecting parts. When this connecting part is exposed; via the power transmitting rod to the inner end plate, from this to the casting body and further from this partially directly to the wall of the blind bore and, moreover, also for the most part via the steel devils to the wood.
En udførelsesform, som er noget mere kompliceret, men langt mere bekvem at håndtere, har en anden, ydre endeplade, hvis ydre tværsnit er tilpasset tværsnittet af blindboringens åbning, og har i det mindste én kraftoverførende stang, 20 hvis ender er fastgjort til modstående ender af to endepla der. Den ydre endeplade har fortrinsvis et taphul, i hvilket der kan indskrues en forbindelsesdel, fx en trækstang, udefra.An embodiment, which is somewhat more complicated but far more convenient to handle, has a second outer end plate, the outer cross section of which is adapted to the cross section of the aperture of the blind bore, and has at least one power transmitting rod, the ends of which are attached to opposite ends. of two end plates there. The outer end plate preferably has a tap hole into which a connecting part, for example a drawbar, can be screwed in from the outside.
Når støbemassen presses ind, skal den overskydende luft 25 kunne undslippe. Til dette formål har den indre endeplade et fortrinsvis centralt ventileringshul, som står i forbindelse med et ventileringshul i træbygningskomponenten. Hvis der findes et taphul i den ydre endeplade, presses støbemassen ind i blindboringen via taphullet. Luften, som for-30 skydes og er i overskud, undslipper derved gennem ventileringshullet i den indre endeplade og via ventileringsboringen.When the molding material is pressed in, the excess air 25 must be able to escape. For this purpose, the inner end plate has a preferably central vent hole which communicates with a vent hole in the wooden building component. If a tap hole exists in the outer end plate, the molding mass is pressed into the blind bore via the tap hole. The air, which is displaced and is in excess, thereby escapes through the vent hole in the inner end plate and via the vent bore.
Tværsnittet af blindboringen og dermed af den ene eller begge endepladerne er fortrinsvis cirkulært eller i enThe cross section of the blind bore and thus of one or both end plates is preferably circular or in a

3 udførelsesform, der ikke er helt så fordelagtig, rektangulært eller kvadratisk eller i øvrigt, i mindre fordelagtige udførelsesformer, ovalt eller af vilkårlig polygonal form.3 is not as advantageous, rectangular or square or otherwise, in less advantageous embodiments, oval or of any polygonal shape.
De kraftoverførende stænger kan være gevindstænger, for-5 trinsvis stive ståldele. Stængerne kan være svejset ved enderne til modstående sider af endepladerne. Man kan imidlertid ligeledes tilvejebringe boringer i endepladerne til de kraftoverførende stænger, som kan strække sig ind i eller gennem boringerne. Stængerne kan derefter fastgøres 10 på ydersiderne af endepladerne på vilkårlig egnet og i og for sig kendt måde.The power transmitting rods may be threaded rods, preferably rigid steel parts. The rods may be welded at the ends to opposite sides of the end plates. However, bores can also be provided in the end plates for the power transmitting rods which may extend into or through the bores. The rods can then be secured 10 to the outside of the end plates in any suitable and per se known manner.
En specielt fordelagtig, ikke-fast forbindelse i forbindelsesdelen opnås ved tilvejebringelse af fire kraftoverførende stænger, som er placeret symmetrisk, set i tværsnit, i 15 hjørnerne af et kvadrat. Tværsnittet af og afstanden mellem de kraftoverførende stænger vælges på en sådan måde, at de stangformede dyveler strækker sig vinkelret på stængerne og trænger ind i rummene mellem stængerne. Ved hjælp af en skabelon kan ståldyvelerne drives ind i træbygningskompo-20 nenten på en sådan måde, at dyvelerne strækker sig nøjagtigt mellem de kraftoverførende stænger. Hvis der benyttes stive ståldele med riflet overflade, opnås der en sikker kraftoverførsel i den hærdede sammensatte blok. Der benyttes fortrinsvis epoxyharpiks som støbemasse.A particularly advantageous, non-solid connection in the connector is achieved by providing four power transmitting bars, which are symmetrically, in cross-section, in the 15 corners of a square. The cross-section of and the distance between the power transmitting rods are selected in such a way that the rod-shaped devils extend perpendicular to the rods and penetrate the spaces between the rods. By means of a template, the steel devils can be driven into the wooden building component in such a way that the devils extend precisely between the transmitting rods. If rigid steel parts with corrugated surface are used, a secure power transmission is obtained in the cured composite block. Epoxy resin is preferably used as a molding compound.
25 Forbindelsesdelen ifølge opfindelsen kan samles på meget simpel og hurtig måde. Efter at der i traebygningskomponen-ten er udformet en blindboring og en ventileringsboring, som er åben ind i bunden af boringen, indsættes indsatslegemet (endepladen eller endepladerne med kraftoverførende 30 stænger) i blindboringen. Efter at de stangformede dyveler er drevet ind vinkelret på blindboringens retning, presses støbemassen ind i blindboringen. Når støbemassen er hærdet, hvilket sker meget hurtigt, er forbindelsesdelen klar til videre håndtering af træbygningskomponenten.The connector part according to the invention can be assembled in a very simple and fast way. After a blind bore and a vent bore which is open into the bottom of the bore are formed in the tree building component, the insert body (end plate or end plates with power transmitting rods) is inserted into the blind bore. After the rod-shaped dowels are driven perpendicular to the direction of the blind bore, the molding mass is pressed into the blind bore. When the casting has hardened, which happens very quickly, the connection part is ready for further handling of the wooden building component.

I fig. 5 er vist enden af en træbjælke 2, set i perspektiv, med en blindboring 3, i hvilken der skal indsættes og fastgøres et stålindsatslegeme 1.In FIG. 5 is a perspective view of the end of a wooden beam 2 with a blind bore 3 into which a steel insert body 1 is to be inserted and secured.
En ventileringsboring 4, hvis funktion vil blive forklaret 20 nedenfor, er åben ind i bunden af blindboringen 3.A vent bore 4, the function of which will be explained 20 below, is open into the bottom of the blind bore 3.
Indsatslegemet 1 har en første endeplade 5, som senere lokaliseres indvendigt, en anden endeplade 6, som senere lokaliseres på ydersiden med yderfladen fortrinsvis flugtende med bjælken 2's endeplan, samt to kraf tover før ende 25 stænger 7 og 8, der er svejset i begge ender til endepladerne 5 og 6. De kraftoverførende stænger 7 og 8 er i denne udførelsesform stive ståldele med riflet overflade. Den første endeplade 5 har et centralt ventileringshul 10. Den ydre endeplade 6 har en central gevindåbning 9.The insert body 1 has a first end plate 5, which is later located internally, a second end plate 6, which is later located on the outside with the outer surface preferably flush with the end plane of the beam 2, and two force ropes before end 25 bars 7 and 8 welded at both ends. to the end plates 5 and 6. The power transmitting rods 7 and 8 in this embodiment are rigid corrugated steel parts. The first end plate 5 has a central vent hole 10. The outer end plate 6 has a central thread opening 9.
30 Blindboringen 3 er dimensioneret på en sådan måde, at ydersiden af endepladen 6 flugter med bjælken 2's endeplan, når indsatslegemet 1 er skubbet helt ind i blindboringen. Efter at indsatslegemet 1 er blevet indsat, drives stangformede dyveler eller tappe 11a, 11b og 11c ind i træbjælken fraThe blind bore 3 is dimensioned in such a way that the outside of the end plate 6 aligns with the end plane of the beam 2 when the insert body 1 is pushed fully into the blind bore. After the insert body 1 has been inserted, rod-shaped devils or pins 11a, 11b and 11c are driven into the wooden beam from

5 henholdsvis oversiden og den venstre side vinkelret på blindboringen og indsatslegemet l. De stangformede dyveler 11a, 11b og 11c har sådanne længder, at de trænger næsten helt gennem bjælken 2's højde eller bredde. Den inddrevne 5 stangformede dyvel 11a strækker sig mellem de to kraftoverførende stænger 7 og 8. De stangformede dyveler 11b og 11c drives ind fra siden og indeslutter de to kraftoverførende stænger 7 og 8. Dette er vist detaljeret i fig. 4. De to endeplader 5 og 6 har et ydre tværsnit, som i alt væsent-10 ligt svarer til tværsnittet af blindboringen 3's åbning. Blindboringen er kun ganske lidt større. I fig. 4 er ligeledes vist hvorledes projektionen af ståldyvelerne 11a, 11b og 11c er placeret på endepladen 5's plan på selve endepladen. De inddrevne ståldyveler forhindrer således, at ind-15 satslegemet 1 kan trækkes ud af blindboringen 3.5, respectively, the upper side and the left side perpendicular to the blind bore and the insert body 1. The rod-shaped devils 11a, 11b and 11c have such lengths that they penetrate almost completely through the height or width of the beam 2. The retracted 5 rod-shaped dowel 11a extends between the two power-transmitting rods 7 and 8. The rod-shaped dowel 11b and 11c are driven in from the side and enclose the two power-transmitting rods 7 and 8. This is shown in detail in FIG. 4. The two end plates 5 and 6 have an outer cross-section which corresponds substantially to the cross-section of the opening of the blind bore 3. The blind bore is only slightly larger. In FIG. 4 is also shown how the projection of the steel devils 11a, 11b and 11c is located on the plane of the end plate 5 on the end plate itself. The recovered steel devils prevent the insert body 1 from being pulled out of the blind bore 3.
Når indsats legemet 1 er lejret i blindboringen 3, og ståldyvelerne er drevet ind, presses der epoxyharpiks ind i blindboringen gennem taphullet 9 i den ydre endeplade 6.When the insert body 1 is housed in the blind bore 3 and the steel devils are driven in, epoxy resin is pressed into the blind bore through the tap hole 9 in the outer end plate 6.
Den overskydende luft undslipper herved gennem ventile-20 ringshullet 10 i den indre endeplade 5 og den tilstødende ventileringsboring 4 i træbjælken. Når epoxyharpiksen er hærdet, danner harpiksen et støbt fyldlegeme, i hvilket de kraftoverførende stænger 7 og 8 og de stangformede dyveler 11a, 11b og 11c er fastgjort i blindboringen. Disse dele 25 danner således sammen en sammensat blok, der er så stramt forbundet med træbjælken 2, at blokken kan optage overordentlig store trækbelastninger.The excess air thereby escapes through the ventilation hole 10 in the inner end plate 5 and the adjacent ventilation bore 4 in the wooden beam. When the epoxy resin is cured, the resin forms a molded filler body in which the power transmitting rods 7 and 8 and the rod-shaped dowels 11a, 11b and 11c are secured to the blind bore. Thus, these parts 25 together form a composite block which is so tightly connected to the wooden beam 2 that the block can absorb extremely large tensile loads.
Ståldyvelerne lla, 11b og 11c har H-formet tværsnit, således som det er vist specielt i fig. 5 for dyvelen lla.The steel dividers 11a, 11b and 11c have H-shaped cross-sections, as shown especially in FIG. 5 for the devil lla.
30 Disse stangformede dyveler er fordelagtige ved, at de kan drives ind i træet, uden at der forud skal være udformet boringer. I stedet for stangformede dyveler med H-formet tværsnit kan der også benyttes stangformede dyveler med cirkulært tværsnit. I betragtning af den belastning, som må 35 forventes, skal de sidstnævnte imidlertid have et sådant 630 These rod-shaped devils are advantageous in that they can be driven into the tree without the need for bores. Instead of rod-shaped dowels with H-shaped cross-section, rod-shaped dowels with circular cross-section can also be used. However, given the load to be expected, the latter should have such a 6

tværsnit, at der skal være udformet boringer i træbjælken forud til disse runde dyveler.cross section, that bores must be formed in the wooden beam prior to these round devils.
En forbindelsesdel, fx en forbindelsesdel med en gevindbolt 12 (se fig. 5) kan skrues ind i taphullet 9 i den ydre 5 endeplade 6.A connecting part, for example a connecting part with a threaded bolt 12 (see Fig. 5) can be screwed into the pin hole 9 in the outer end plate 6.
Den i fig. 4 og 5 viste udførelsesform har to kraftoverførende stænger. Man kan imidlertid også tilvejebringe blot én kraftoverførende stang 70, således som det er vist i fig. J3.
